in reply to monitor iperf from perl

One approach would be to leverage the tasklist command from the command prompt. Your script can call that every so often to check to see if iperf.exe is running and then restart it if it isn't. Not sure what iperf.exe is, but you also might want to add a check to see if properly completed its work and cleanly exited.

    Just a guess: 
    IPERF(1)                         User Manuals                         IPERF(1)

NAME
       iperf - perform network throughput tests

...

DESCRIPTION
       iperf is a tool for performing network throughput measurements.  It can
       test either TCP or UDP throughput.  To perform an iperf test  the  user
       must establish both a server (to discard traffic) and a client (to gen‐
       erate traffic).

    It doesn't seem like something that would crash often...

      Ordinarily it doesn't, but I'm operating it using a processor who's core voltage is intentionally lower than spec, I occasionally get "stack overflow" and it's ko'd at that point.

    I think that may be the correct approach, I am going to try that.
